Abstract

See full text

A user equipment (UE) may perform a random access procedure to synchronize with a network for uplink and/or downlink communication. The UE may transmit a first type of random access transmission that includes transmitting a preamble or a second type of random access transmission that includes transmitting a preamble and a random access message. The second type may result in reduced delay but may have lesser SNR tolerance than the first type. In some aspects, the UE may determine whether to transmit the first type or the second type, and may transmit the first type or the second type in a random access channel portion of a slot. The random access channel portion of the slot may be occupied by portions of either the first type of random access transmission or the second type of random access transmission, thereby enabling flexible utilization of multiple types of random access procedure.
